Protecting Oahu's Groundwater Aquifer at Red Hill

The Board of Water Supply (BWS) remains steadfast in our commitment to providing safe, dependable and affordable water for Oahu's needs today and in the future. This includes taking a strong stance when protecting our groundwater aquifers.

In January 2014, the U.S. Navy reported a 27,000 gallon leak of jet fuel from Tank 5 at its Red Hill Bulk Fuel Storage Facility. This underground storage tank (UST) – along with 19 others like it in the Red Hill area – is able to contain up to 12.5 million gallons of fuel for the U.S. Navy. These tanks are located 100 feet above the groundwater aquifer, which the BWS uses to provide water to residents from Moanalua to Hawaii Kai.
